Vitamin B12 or folate deficiency anaemia - Diagnosis

Correspondingly, combined treatment with sertraline, an inhibitor of serine/glycine conversion, and radiotherapy significantly impairs the proliferation, clonogenicity and stem cell self-renewal capacity of NSCLC cells, and also effectively suppresses tumor growth in in vivo experiments ( 4.1.2 Colorectal cancer Genes involved in the SSP are generally highly expressed in colorectal cancer and are correlated with unfavorable patient prognosis ( Meanwhile, activation of the Wnt pathway in turn promotes the transcription of SHMT2, forming a positive feedback loop of the SHMT2Wnt/-catenin axis that further strengthens the metabolic output of the SSP ( Clinical samples have confirmed that approximately 82% of OXPHOS-deficient colorectal cancer tissues harbor mtDNA mutations, and the SSP activity in these tumors is significantly higher than that in normal tissues ( The transcription factor FOXC1 has also been shown to reprogram serine metabolism under serine-deprived conditions to promote colorectal cancer proliferation and 5-fluorouracil resistance
